DIFFERENTIAL PRESSURE - Coulton Instrumentation

Zero/span adjustment :Zero and span are adjustable from the HHC (1) . Zero andspan are also adjustable externally from the adjustmentscrew (span adjustment is not available with 9th digitcode “L, P, M, Q, S, N”).Damping :Adjustable from HHC (1) or local adjustment unit with LCDdisplay.The time constant is adjustable between 0 to 32 seconds.Zero elevation / suppression :-100% to +100% of URLNormal / reverse action :Selectable from HHC (1)Indication :Analog indicator or 5-digit LCD meter, as specied.Burnout direction : Selectable from HHC (1)If self-diagnostic detect transmitter failure, the analogsignal will be driven to either “Output Hold”, “OutputOverscale” or “Output Underscale” modes.“Output Hold” :Output signal is hold as the value just before failure happens.“Output Overscale” :Adjustable within the range 20.0mA to 22.5mA fromHHC (1)“Output Underscale” :Adjustable within the range 3.2mA to 4.0mA from HHC (1)Under scaleBurnout3.2 4 20 22.5 [mA]Over scaleBurnoutNormal operating rangeProbable under rangeProbable over rangeOutput limits conforming to NAMUR NE43 by order.Loop-check output :Transmitter can be congured to provide constant signal3.2mA through 22.5mA by HHC (1) .Temperature limit :Ambient : -40 to +85°C(-20 to +80°C for LCD indicator)(-40 to +60°C for arrester option)(-10 to +60°C for uorinated oil lled transmitters)For explosionproof units (ameproof or intrinsic safety),ambient temperature must be within the limits speciedin each standard.Process : -40 to +120°C for silicone ll sensor-20 to +80°C for uorinated oil ll sensorStorage : -40 to +90°CHumidity limit :0 to 100% RHCommunication :With HHC (1) (Model FXW, consult datasheet N° EDS8-47),following items can be remotely displayed or congured.Note: HHC’s version must be higher than 7.0(or FXW 1- 4), for FCX-AII. for supporting theseitems : “Saturate current”, “Write protect”, and “History”.ItemsFuji Protocolwith FXWHart ® ProtocolDisplay Set Display SetTag No. v v v vModel No. v v — —Serial No. & Software Version v — v —Engineering unit v v v vRange limit v — v —Measuring range v v v vDamping v v v vLinear v v v vOutput modeSquare root v v v vBurnout direction v v v vCalibration v v v vOutput adjust — v — vData v — v —Self diagnoses v — v —Printer (In case of FXW withprinter option)v — — —External switch lock v v v vTransmitter display v v v vLinearize* v v — —Rerange v v v vSaturate current v v v vWrite protect v v v vHistory– Calibration history– Ambient temperature history(Note) (1) HHC: Hand Held Communicator*Local configurator with LCD display (option) :Local congurator with 3 push button and LCD display cansupport all items (Fuji Protocol list) except “Linearize” function.Programmable output linearization function :Output signal can be characterized with “14 points linearapproximation function” from HHC (1) .Performance specifications for linear outputReference conditions, silicone oil ll, 316SS isolating diaphragms, 4 to20mA analog output in linear mode.Accuracy rating :(including linearity, hysteresis, and repeatability)Max span : 32kPa models and aboveFor spans greater than 1/10 of URL:±0.065% of span or ±0.04% of span (optional)For spans below 1/10 of URL:0.1 × URL± 0.015+0.05 % of spanvvSpanv—( )Max span 20MPa models :For spans greater than 5MPa :±0.1% of spanFor spans below 5MPa :5MPa±(0.05+0.05 % of spanSpan )Max span 1kPa, 6kPa models :For spans greater than 1/10 of URL:±0.1% of spanFor spans below 1/10 of URL :( )Stability :±0.1% of upper range limit (URL) for 10 years for 6th digitcode 3, 5, 6, 8 and 9.Temperature effect :Effects per 28°C change between the limits of -40°C and +85°Cvv0.1 × URL± 0.05+0.05 % of spanSpanRange code(6th digit in code Zero shiftTotal effectsymbols)“1”/1kPa {10mbar}±URL“2”/6kPa {60mbar}( 0.125+0.1 )%±URL( 0.15+0.1 ) %SpanSpan“3”/32kPa{320mbar}“5”/130kPa{1300mbar}URLURL± ( 0.075+0.0125“6”/500kPaSpan) % ± ( 0.095+0.0125Span ) %{5000mbar}“8”/3000 kPa{30000mbar}“9”/20000 kPa{200000mbar}Double the effects for material code (7th digit in codes symbols)“H”, “M”, “T”v—3
